It does seem that way. And not just the restoration of parts. Even some of the old used parts. It's funny,you'll see parts that were common on a lot of different Camaros but when there listed for sale the heading will say"Z28", "SS", "COPO", "Yenko. And the price they want will show it. That's where knowledge comes in. And I'm thankful for CRG, they gives me that knowledge.
